[QUOTE="bimmerman, post: 51910, member: 126"] Yup, playing with tire pressure can only do so much and is only effective for high speed and medium speed corners. But be warned that things can really get out of hand during high speed corners! You could rip your tires to shreads!!! Or worse still, your rims could catch the tarmac and you could flip over!!! Remember the A-Class Elk test? When you lower your tire pressure, your sidewall will flex more and it's this flexing motion that causes the tire to lose grip as part of the contact patch is lifted off the ground and grip is compromised. Tuning via suspension like stiffer ARB for the rear is really the way to go as you're not making compromises like reducing your tires effectiveness which is not a good thing to do for the reason mentioned above. But since Bazet is making a stunt video, temporarily lowering the rear tire pressure to invoke some oversteer drama should be ok. Unless he's on a Hollywood budget for a total suspension overhaul. :dunno: p/s: if Bazet flips his car over, it would be one hell of a low budget video with a hollywood budget :rofl: [/QUOTE]
